DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1

[0031] The utility model provides a hydrogen water machine hydrogen water mixing regulating device, such as Figure 1-6 As shown, the hydrogen-water mixing and regulating device comprises a hydrogen-water chassis 1 and a hydrogen dissolving box 4 which is arranged on the hydrogen-water chassis 1 and is connected to the hydrogen exhaust pipe 33 of the electrolysis mechanism 3, and a controller 2 is arranged on the hydrogen-water chassis 1;

[0032] Wherein, the electrolysis mechanism 3 is a PEM electrolyzer;

[0033] A hydrogen-water mixing and regulating component connected to the hydrogen exhaust pipe 33 is provided at the bottom of the hydrogen dissolving box 4, and the hydrogen-water mixing and regulating component includes a liquid inlet pipe fixedly plugged into the bottom end of the hydrogen dissolving box 4, and a high-pressure atomizing nozzle 411 fixedly installed on the liquid inlet pipe is provided inside the hydrogen dissolving box 4, and a booster self-priming pump 5 for sucking hydrogen and pure water is installed on the liquid inlet pipe; by merging the liquid inlet pipe and the hydrogen exhaust pipe 33 into a liquid supply pipeline, the hydrogen can be pre-mixed with the pure water in the liquid inlet pipe under the action of the booster self-priming pump 5, and the pure water and hydrogen are simultaneously sprayed from the high-pressure atomizing nozzle 411 into the bottom of the hydrogen dissolving box 4 under the action of pressure, and the high-pressure atomizing nozzle 411 can decompose the pure water into very fine water droplets, increase the surface area of ​​the water, and thus greatly increase the contact area between hydrogen and water. A larger contact area helps to accelerate the dissolution process of hydrogen in water; hydrogen and water begin to mix preliminarily during the spraying process through the nozzles, and then further diffuse and mix in the hydrogen dissolving box 4, so that the hydrogen can be distributed more evenly to avoid excessive hydrogen concentration in local areas; the spraying process itself also provides power, which is equivalent to forming a stirring effect at the bottom of the hydrogen dissolving box 4, which helps to break possible bubbles and promote hydrogen to dissolve into water faster; compared with static mixing or simple injection methods, this method can significantly improve the efficiency and rate of hydrogen dissolution, especially in application scenarios where hydrogen aqueous solution needs to be prepared quickly; hydrogen atomized under high pressure will form very fine bubbles, and these micro-nano bubbles have a large specific surface area, which helps hydrogen to dissolve quickly in water; the tiny bubbles rise slowly in water, prolonging their residence time in water, which is conducive to sufficient gas exchange and improving dissolution efficiency; compared with other methods that require continuous stirring or use chemical methods to promote dissolution, high-pressure atomization may be a more energy-saving and efficient mixing method; this method does not involve chemical additives, so it will not cause additional pollution to the water quality and maintain the purity of hydrogen water;

[0034] When in use, firstly, the conventional water source and the pure water source from the outside are connected to the first water inlet pipe 31 and the liquid inlet end of the liquid inlet pipe respectively, and then the hydrogen generated by electrolysis is discharged into the hydrogen exhaust pipe 33 under the action of the electrolysis mechanism 3, and then the hydrogen in the hydrogen exhaust pipe 33 is sucked by the booster self-priming pump 5, and at the same time, the pure water entering from the liquid inlet pipe port is sucked, so that the hydrogen is pre-mixed with the pure water under the action of pressure inside the liquid inlet pipe, and then the pre-mixed pure water and hydrogen are sprayed into the bottom of the hydrogen dissolving box 4 through the high-pressure nozzle under the action of the booster self-priming pump 5, and then the hydrogen dissolving box 4 is pre-mixed with the pure water under the action of the booster self-priming pump 5. Under high pressure injection, pure water and hydrogen will form very fine water droplets and bubbles, increasing the surface area of ​​water. These micro-nano bubbles have a large specific surface area, thereby greatly increasing the contact area between hydrogen and water, which helps hydrogen to dissolve quickly in water. The tiny bubbles rise slowly in water, which prolongs their residence time in water, is conducive to full gas exchange, and improves dissolution efficiency. Hydrogen and water begin to mix preliminarily during the injection process, and then further diffuse and mix in the hydrogen dissolving box 4, so that hydrogen can be distributed more evenly to avoid excessive hydrogen concentration in local areas.

[0035] Furthermore, the liquid inlet pipe is connected to the hydrogen exhaust pipe 33 via a three-way joint 6 .

[0036] Furthermore, the liquid inlet end of the three-way connector 6 is fixedly connected to a filter assembly 7 for filtering pure water; the filter assembly 7 uses a DSC filter element to reduce the TDS value until it returns to zero, purifying the water quality and removing the total dissolved solid content in the water.

[0037] Furthermore, one-way valves are fixedly installed on the hydrogen exhaust pipe 33 and the liquid inlet pipe; the one-way valves are used to prevent the backflow of gas and liquid.

[0038] The electrolysis mechanism 3 is connected with a first water inlet pipe 31 and a first water outlet pipe 32 , and the first water inlet pipe 31 is located above the first water outlet pipe 32 .

[0039] The hydrogen dissolving box 4 is also connected to a hydrogen mixing drainage pipe 41 .

[0040] Example 2

[0041] Refer to the attached Figure 4 and attached Figure 6As shown, a hydrogen flow detector 331 is arranged in the hydrogen exhaust pipe 33; a liquid flow detector 61 connected to the controller 2 is arranged in the liquid outlet end of the filter assembly 7; the signal output end of the liquid flow detector 61 and the signal output end of the hydrogen flow detector 331 are both electrically connected to the signal input end of the controller 2, and the signal output end of the controller 2 is electrically connected to the current regulator of the electrolysis mechanism 3; by the hydrogen flow detector 331 arranged in the hydrogen exhaust pipe 33, the hydrogen content flowing through the hydrogen exhaust pipe 33 can be measured, and by installing the liquid flow detector 61 after the filter assembly 7, the amount of water detected by the liquid flow detector 61 is made more accurate; by the arrangement of the hydrogen flow detector 331, the liquid flow detector 61 and the controller 2, it is convenient to obtain the hydrogen content in the air pipe and the circulation volume of the water flow in the water pipeline in real time, so that the device can set the machine parameters according to the water flow volume and the hydrogen concentration of the water body, so as to achieve different concentration requirements for different water volumes, improve the user experience, and can accurately adjust and control the hydrogen content contained in the pure water.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
